TECHNICAL FIELD

This document relates generally to lift floors, and more particularly to lift floors positioned in utility vehicle storage areas.

BACKGROUND

Getting cargo into and out of vehicle storage areas is an age-old dilemma for vehicle owners. Bulky cargo is difficult to maneuver into the storage area and difficult to position once inside the storage area. Similarly, heavy cargo can be difficult to lift from ground level to a lip of the storage area, and is often at least as difficult to lower onto the floor of the storage area. Further difficulty can be encountered when removing bulky or heavy cargo from the storage area.

In order to overcome and alleviate some of the issues in this area, the prior art discloses several mechanisms for raising and lowering a floor within a storage area such as the trunk of an automobile. One example of the prior art includes the lifting mechanism described in U.S. Pat. No. 4,969,793 to Pawl. The mechanism includes a power-operated lift that is adapted to be mounted over a wheel well covering a portion of an automobile trunk. The lift has linkages for raising or lowering a load-supporting floor with respect to the trunk floor in a vertical direction. The load-supporting floor can also be manually moved in a horizontal direction in order to remove the load from the trunk and pivoted about the attached supporting frame when the load-supporting floor is positioned on the trunk floor. Pivoting the load-supporting floor in this manner provides access to the wheel well portion of the trunk floor positioned beneath the load-supporting floor.

While the prior art lift mechanisms are sufficient to provide assistance with loading and unloading cargo into an automobile's storage area and providing access to the wheel well including the spare tire and related tools, specific vehicle designs demand even more functionality from such mechanisms. With the advent of utility vehicles, such as sport utility vehicles and crossover utility vehicles, for example, the footprint of the area available for storage has decreased when compared to the more traditional automobile storage areas. The smaller footprint is created primarily by the narrowing of the storage area from the rear of the utility vehicles inward in order to accommodate additional passenger space within the vehicle (e.g., third row seating). In order to maintain a sufficient square footage for cargo storage, the storage areas are necessarily deeper from top to bottom than previous storage areas.

As a result, the storage area designs of utility vehicles generally result in the stacking of belongings and, more importantly, placing an initial layer of belongings on a floor of the storage area which is often below the upper lip of an access area adjacent a rear lift gate. Depending on the platform on which the utility vehicle is built, the floor of the storage area where the initial layer of belongings are placed may be significantly below the upper lip creating even greater challenges when loading heavy and/or bulky cargo and unloading same.

Given the size limitations of utility vehicle storage areas, modern lift mechanisms should be designed to maximize the storage area footprint by covering a maximum portion of the footprint with a load-supporting floor instead of a central portion of the storage area as shown in the Pawl patent. Utilization of substantially the entirety of the storage area floor, however, results in limited access within the cargo area for service or access to a spare tire compartment and further limits the available storage area. In today's sports utility and crossover utility vehicles, it is therefore desirable for the load-supporting floor of the lift mechanism to be removable from the vehicle.

Removing the floor provides greater ease of access to wiring for vehicle lights, power outlets, and speakers, for example, which are often positioned within or are directly adjacent the storage area of utility vehicles and often require access for service. Even more, although the floor can be pivoted to provide access to a spare time compartment, some customers prefer to remove the load-supporting floor to access the spare time and related tools instead of finessing the spare tire out from underneath the pivoted floor and over the elevated access lip of the storage area. This is particularly the case in utility vehicles with a lowered storage area floor. Still, other customers desire to simply remove the load-supporting floor to gain additional cargo storage volume when required.

This document relates to a lift assembly for a utility vehicle storage area that provides a floor capable of raising and lowering cargo within the storage area. Even more, the lift assembly utilizes rollers to create a pivot point around which the floor pivots to allow access to a wheel well and spare time. Utilizing the rollers in this manner allows the floor to be removed when desired simply by lifting the floor from the storage area. Advantageously, this allows for the floor to be separated from the lift assembly and completely removed from the utility vehicle when desired. This removal provides easier access to the spare tire compartment within the storage area and allows for easier access to underlying wiring and systems within the vehicle for service.

DETAILED DESCRIPTION

Reference is now made to FIG. 1 which broadly illustrates an embodiment of a lift assembly 10 having a removable floor 12. The floor 12 is supported by a scissor mechanism 14 which is raised from a neutral (or lowered) position to an elevated position by an actuator 16. Scissors mechanisms utilize linked, folding supports in a criss-cross or “X” pattern which are typically attached to a base. Extension is achieved by applying pressure to an outside pair of supports located at one end of the mechanism thereby elongating the crossing pattern. The applied pressure can be achieved through hydraulic, pneumatic, mechanical, or simply muscular means. Of course, the supports and base can be manufactured of metals, plastics, and other materials and can take many shapes to accommodate particular design requirements or features.

As shown in FIG. 2, the scissor mechanism 14 includes two pairs of first and second pivotally connected supports 20, 22, and a base 18. The first and second pivotally connected supports 20, 22 and base 18 are manufactured from a lightweight extruded aluminum in the described embodiment. The first supports 20 are attached adjacent a first end 24 to the base 18. More specifically, the first supports 20 are attached to a rear area 26 of the base 18. Similarly, the second supports 22 are pivotally connected to the first supports 20 at pivot point 28 creating an X-type configuration. A roller 30 is attached adjacent a first end 32 of each of the second supports 22. The rollers 30 are confined within the base 18 for movement therein as will be described in more detail below. In another embodiment, a member (not shown) may replace the roller. The member may be spherical shaped, semi-spherical shaped, flat or generally any shape so long as the member is capable of moving along the base. A second end 34 of the second supports 22 is pivotally attached to guide members 36 to allow the scissor mechanism 14 to be raised and lowered.

One or more lateral cross braces 38 may also be utilized. In the described embodiment, lateral tubular cross braces 38 extend between pairs of first and second pivotally connected supports. A first lateral brace 40 is attached adjacent the first ends 32 of the second supports 22 near the rollers 30. A second lateral brace 42 is attached to the second supports 22 at a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As will be described below, the second lateral brace 42 is attached near an attachment point of the actuator 16. A third lateral brace 44 is attached adjacent the second ends 46 of the first supports 20 near the guide members 36 and floor 12 (not shown in this figure). Of course, additional or fewer braces may be utilized depending on any number of factors, for example, the overall dimensions of the lift mechanism or the expected loads on the floor.

In the described embodiment, the base 18 includes a pair of guide members 48, as shown in FIG. 1, which may be secured to a frame of the utility vehicle. In the described embodiment, angle brackets 50 are attached to ends of the base 18 and bolted to the vehicle. A lateral brace 52 extending between base guide members 48 may also be utilized. As shown, the lateral brace 52 may likewise be bolted to the vehicle adjacent the base guide members 48 and may be formed to extend into the wheel well of the vehicle to deter any shifting of the base 18 during use. Of course other methods for securing the base to the vehicle and deterring shifting may be used in accordance with the broad teachings herein. The guide members 48 of the described base are C-shaped channels within which the scissor mechanism rollers 30 are allowed to move. The C-shaped channels 48 limit the rollers 30 to a linear direction forcing the scissor mechanism 14 to be raised and lowered.

The actuator 16 is pivotally attached at its first end 54 to a first end of the first support 24 at the rear of the base 26. A second end 56 of the actuator 16 is likewise pivotally attached to the second support 22 at a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As the actuator 16 extends, the second end 56 of the actuator forces the second support 22 upward while the first end 54 of the actuator rotates about its pivotal attachment to the first end of the first support 24. Raising the second support 22 necessarily raises the first support 20 thereby raising the floor 12. In reverse manner, as the actuator 16 retracts, the second end of the actuator 56 pulls the second support 22 downward reversing the upward movement described above.

As shown in FIG. 3, the actuator 16 may be retracted to a fully retracted position wherein the scissor mechanism 14 is substantially flat. This is the neutral or lowered position. In this position, the actuator 16 is positioned substantially or completely within the first support 20. The first and second supports 20, 22 in the described embodiment are generally U-shaped channels which provide structural integrity while maintaining a light weight. As shown in FIG. 1, the actuator 16 is pivotally secured within the U-shaped channel of the second support 22. In this manner, the actuator 16 is received within the U-shaped channel of the second support 22 as the scissor mechanism 14 is lowered to the neutral position and does not hinder the range of motion of the scissor mechanism.

As is best shown in FIG. 1, a second actuator 16 is attached to the second pair of supports to provide additional stability during operation of the scissor mechanism 14. More specifically, a first end of the second actuator 60 is pivotally attached to a second end of the first support 46 at the rear of the base 26. A second end of the second actuator 62 is likewise pivotally attached to the second support 22 at a position between the pivot point 28 formed by the first and second supports and the second end of the second support 34. As the actuator 16 extends, the second end of the strut 62 extends with the second support 22 upward while the first end of the actuator 60 rotates about its pivotal attachment to the first end of the first support 24. As before, the actuator 16 is pivotally secured within a U-shaped channel of the second support 22. In this manner, as the scissor mechanism 14 is lowered to the neutral position, the strut is positioned within the U-shaped channel of the second support and does not hinder the range of motion of the scissor mechanism.

As best shown in FIG. 4, a plurality of rollers 64 are attached to an underside of the floor 12 for engagement with guide members 36 attached to the scissor mechanism 14. In the described embodiment, four rollers 64 are attached to the underside of the floor. Specifically a first pair of rollers 68 is attached adjacent a rear edge 70 of the floor 12 and a second pair of rollers 72 attached between a front edge 74 of the floor and the rear edge of the floor. The rollers 64 are generally positioned and secured within the guide members 36, or channels, within which the rollers are limited to movement along a linear direction.

The guide members 36 are attached to the scissor mechanism 14 for movement therewith and in the described embodiment include cutouts 76 positioned between the front edge 74 and the rear edge 70 of the floor. Specifically, as best shown in FIG. 2, the cutouts 76 are positioned adjacent the second pair of rollers 72. This allows the second pair of rollers 72 to pass through the cutouts 76 when the floor 12 is rotated to a pivoted position as shown in FIG. 4.

As shown in FIG. 5, a detent 78 protrudes into one of the guide members 36 preventing rotation of the roller 64. A detent is a device used to mechanically resist or arrest the rotation of a wheel, roller, or axle. Such a device can be anything ranging from a simple metal pin to a machine. The detent 78 in the described embodiment is a spring detent but, as noted, the detent may take any form sufficient to resist or arrest the rotation of the roller 64. Even more, a second detent (not shown) may be utilized in like manner in association with a second roller 64.

As shown, the roller 64 is positioned adjacent the detent 78 which prevents rotation thereof and locks the floor 12 into a neutral or fully installed position. This prevents movement of the floor 12 due to cargo shifting, particularly when the vehicle is in transit. In this neutral position, the second pair of rollers 72 is adjacent the cutouts 76 in the guide members 36 allowing the second pair of rollers to pass through the cutouts as the floor 12 pivots upward. Pivoting of the floor in this manner can take place when the floor is in the neutral position, the elevated position, or any position between the neutral and elevated positions. Even more, holding the roller 64 in the neutral position such that the roller is in a position near a rear of the guide member 36 allows the floor 12 to pivot around the roller 64 to a pivot position. Forming a pivot point 80 utilizing a roller 64 attached to the floor allows for the removal of the floor when desired. Removal is accomplished by pivoting the floor 12 so the second pair of rollers 72 pass through the guide member cutouts 76 and pulling the floor in a direction out of the vehicle until the first pair of rollers 68 are adjacent the guide member cutouts. Lifting the floor 12 such that the first pair of rollers 68 pass through the guide member cutouts 76 frees the floor from the lift assembly 10.

Installation of the floor 12 is an easy, reverse process wherein the first pair of rollers 68 are positioned over the guide member cutouts 76 and allowed to enter the guide members 36. Applying a rearward force to the floor 12 moves the first pair of rollers 68 along the guide members 36 until the second pair of rollers 72 is positioned adjacent the guide member cutouts 76. Allowing the second pair of rollers 72 to enter the guide members 36 and applying additional rearward force overcomes the detent 78 from a front side allowing the first pair of rollers 68 to be seated on a rear side of the detent in the neutral or fully installed position.

In order to move the floor 12 to the extended position shown in FIG. 6, a force is applied to the floor sufficient to overcome the detent 78 allowing the plurality of rollers 64 to move linearly within the guide members 36. The floor 12 can be extended to any length which, in the described embodiment, is limited by the length of the guide member 36. Other embodiments may include one or more additional detents or an intermediate stop between the neutral position and a fully extended position. It is important to note that the floor can be extended from the neutral position, the elevated position, or any position between the neutral and elevated positions.

In another embodiment, the lift assembly 10 for a utility vehicle described above and all of the described variations thereof are incorporated into a utility vehicle (not shown).

In another aspect of the invention, a method of removing a floor 12 from a lift assembly 10 of a utility vehicle storage area is illustrated in FIGS. 7A-7C. In the first step shown in FIG. 7A, a scissor mechanism 14 supporting the floor 12 is actuated to move the floor to a removal position. The removal position can be the neutral or fully installed position, the elevated position, or any position between the neutral and elevated positions. This allows the vehicle operator or service technician to adjust the height of the floor dependent upon the user's height, desired method of lifting the floor, or other factors.

In the removal position, the vehicle operator or service technician pivots the floor 12 to a pivoted position. This is accomplished by lifting the front edge of the floor 74 allowing the second pair of rollers 72 to pass through the guide member cutouts 76 as shown by action arrow A in FIG. 7B. Once the floor 12 is in the pivoted position and the front edge 74 lifted freeing the second pair of rollers 72, a force is applied to the floor sufficient to release the roller 64 from the detent 78.

As described above, this allows the floor 12 to be pulled in a direction out of the vehicle as shown by action arrow B in FIG. 7B. In accordance with the method, the pulling force is maintained until the first pair of rollers 68 is adjacent the guide member cutouts 76. A rear edge of the floor 70 can then be lifted as shown by action arrow C in FIG. 7C such that the first pair of rollers 68 pass through the guide member cutouts 76 thereby freeing the floor 12 from the lift assembly 10. The floor 12 can then be set aside during servicing of the vehicle, accessing the spare tire and related tools, or throughout a trip in which the entirety of the storage area is desired for cargo.

In another aspect of the method of removing the floor 12 from the lift assembly 10 of the utility vehicle storage area, the scissor mechanism 14 may be braced utilizing at least one lateral support 38 as shown in FIG. 2. In the above described embodiment, three lateral supports 40, 42, 44 are used to brace the scissor mechanism 14.

Re-installation of the floor 12 is an easy, reverse process wherein the floor is positioned such that the first pair of rollers 68 are over the guide member cutouts 76. The floor 12 is lowered allowing the first pair of rollers 68 to enter the guide members 36. Applying a rearward force to the floor 12 moves the first pair of rollers 68 along and within the guide members 36 until the second pair of rollers 72 is positioned adjacent the guide member cutouts 76 in a pivoted position. Allowing the second pair of rollers 72 to enter the guide members 36 and applying additional rearward force overcomes the detent 78 from a front side thereof allowing the first pair of rollers 68 to be seated on a rear side of the detent in the removal position. As noted above, the removal position can be the neutral or fully installed position, the elevated position, or any position between the neutral and elevated positions depending on the position of the scissor mechanism 14. Again, this allows the vehicle operator or service technician to adjust the height at which the floor 12 will be re-installed dependent upon the user's height, desired method of lifting the floor, or other factors.

In summary, numerous benefits result from providing a lift assembly 10 for a utility vehicle that can be removed from the assembly and vehicle if desired. The particular design allows for easy removal of the floor 12 without the need for tools or dismantling of the assembly. Advantageously, this allows for the entirety of the storage area to be used, easier access to the spare tire and related tools, and easier access to the underlying wiring and systems during service of the vehicle.
